Document Summary
Week 4 september 30 th , 2015. It has been used synonymously with terms such as arousal, control, and consciousness. These are all clearly very different things. Dichotic listening: participants are exposed to two verbal messages simultaneously and are required to answer questions posed in only one of the messages: selective attention: attending to relevant information and ignoring irrelevant information. People must filter out information they don"t wish to attend to. Filter: a hypothetical mechanism that would admit certain messages and block others. Selective looking: occurs when we are exposed to two events simultaneously but attend to only one of them: visual analogue of dichotic listening. Early selection: the hypothesis that attention prevents early perceptual processing of distractors: both dichotic listening and selective looking produced results consistent with early selection, attended input directly goes to consciousness, unattended input isn"t perceived. Complex stimuli involve more effort, leading to early selection. Easy stimuli involve less effort, leading to late selection.
